Electric linear actuator design.

A linear actuator uses one of a variety of mechanisms to produce motion in a straight line. Gsa linear slide actuators the gsa linear slide actuator combines an electric rod actuator with guide rods mounting blocks and bearings. Electric linear actuators are an alternative to pneumatic cylinders in several applications because of the flexibility they deliver in the design of production processes and production monitoring systems. A linear actuator is an actuator that creates motion in a straight line in contrast to the circular motion of a conventional electric motor.

These motors have several specific advantages which makes them a popular choice in certain applications over the others. In conveying applications for example diverting and sorting functions are more frequently controlled using electric actuators. A high speed linear actuator would also be rated by the amount of time required to complete its linear travel such as inches per second. The most common design for an electric linear actuator is a dc motor with a transmission usually a worm gear connected to a screw nut assembly.

The rsx press model is an extreme force electric linear actuator that is more efficient reliable and precise than hydraulic cylinders used in pressing applications. Linear actuators are used in machine tools and industrial machinery in computer peripherals such as disk drives and printers in valves and dampers and in many other places where linear motion is required. Linear actuators provide a quiet safe energy efficient and smooth motion. This direct conversion of electrical to mechanical energy results in effective economic linear movement.

Engineering an electric linear actuator electric cylinder system in house is often the most cost and time efficient route to an automated motion solution. This basic design converts the rotational motion in the dc motor to a linear motion. Sometimes you are better off buying. Detailed description of a home build balanced linear actuator for six degree of freedom 6dof motion platform for flight simulator.

Warner linear actuators consist of an electric motor combined with a high efficiency gear train and lead screw. How electric linear actuators contribute to automate the functioning of doors. Roy schreffler design engineer skf. Units are completely self contained and require minimal installation hardware or wiring.

Superb load holding power. The range of motion is called the stroke and can be measured in foot pounds of torque and inches of travel.
